| 摘 要： | 粉煤灰比表面积较大,常被用作吸附材料而广泛应用于污水的处理。主要利用电厂产生的粉煤灰做吸附剂,对生活污水进行处理,考察了pH值、灰水比、粉煤灰粒径、时间等因素对吸附效果的影响。研究结果表明,粉煤灰最佳灰水比为1/30,吸附平衡时间为70min,在弱酸性或弱碱性和较小粒度的条件下,粉煤灰吸附生活污水的效果较好。

| Abstract: | The coal ash is widely used as an absorbent in the sewage treatment because of its certain specific surface area.This paper inspects the effect of pH value,the ratio of ash and water,particle size of the coaL ash and time on treatment of sewage,using the coaL ash as adsorbent.The results shows that the best ratio of ash and watern is 1/30,the balance time of adsorption is 70 minutes.The coal ash has the better adsorption effect on sewage under the conditions of the weak acid or alkaline weak and smaller size life of the coal ash. |
